Gigi Hadid, though, was more apt to show off her goofy side. Scanning her 1,067 Instagram posts, you can literally watch her mature from a 15-year-old part-time model/equestrian/athlete and full-time high school student into a full-time model who knows her best looks inside and out. Gigi may have long ago given up on her signature stick-out-your-tongue look, but remains the cute California girl she's always been.
